Abstract:
Objective To evaluate the clinical trials of cytoreductive surgery (CRS) plus hyperthermic intraperitoneal chemotherapy (HIPEC) on gastric cancer peritoneal carcinomatosis (GC PC).
Methods The published clinical trials of CRS+HIPEC on GC PC were critically evaluated, with survival and safety as the primary endpoints.
Results The natural course of GC PC was < 5 months. CRS+HIPEC could improve the overall survival (OS). In prospective studies, the median OS was 11.0 months in the CRS+HIPEC group. In retrospective studies, the median OS was 13.3 months in the CRS+HIPEC group. The perioperative mortality was less than 6.5%, and there was no statistically significant increase in serious adverse events directly attributable to CRS+HIPEC.
Conclusion CRS+HIPEC is a promising integrated treatment strategy for GC PC to produce improved treatment efficacy, and should be recommended as the first treatment choice for selected patients with GC PC.
